I m trying to use a *chart using JQ widget* ,below snippet contains my controller code, When I m使ajax調用從服務器獲取數據然後 i m able to get the response but the chart takes previous data of that variable i.e. undefined . If i m硬編碼控制器中的相同數據然後工作。 我猜想它的承擔價值，我應該如何發送ajax響應數據到圖表。JQ Widgets圖表與AngularJS顯示錯誤
我對這些事情很陌生，請讓我知道在這種情況下我應該怎麼做才能將數據發送到圖表。
在UI這是我的標籤： -
JQDemo.controller("charts", function ($scope, $timeout,$http) {
\t // prepare chart data as an array
// var sampleData = [
// { State: 'Maharastra', AccountsOpened: 30, VerificationPending: 0, Rejected: 25 },
// { State: 'Karnataka', AccountsOpened: 25, VerificationPending: 25, Rejected: 0},
// { State: 'Tamil Nadu', AccountsOpened: 30, VerificationPending: 0, Rejected: 25 },
// { State: 'AP', AccountsOpened: 20, VerificationPending: 20, Rejected: 25},
// { State: 'Bihar', AccountsOpened: 0, VerificationPending: 20, Rejected: 25 },
// { State: 'Odisha', AccountsOpened: 30, VerificationPending: 0, Rejected: 30},
// { State: 'UP', AccountsOpened: 20, VerificationPending: 40, Rejected: 0 }
// ];
\t
\t var sampleData=[{"AccountsOpened":"2","State":"AP","VerificationPending":"1","Rejected":"1"},{"AccountsOpened":"1","State":"Calcutta","VerificationPending":"2","Rejected":"1"},{"AccountsOpened":"2","State":"Delhi","VerificationPending":"1","Rejected":"5"},{"AccountsOpened":"2","State":"Maharastra","VerificationPending":"1","Rejected":"1"},{"AccountsOpened":"1","State":"Odisha","VerificationPending":"2","Rejected":"1"},{"AccountsOpened":"1","State":"UP","VerificationPending":"1","Rejected":"6"}] ; \t \t \t
// \t var sampleData ;
// \t $http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded; charset=utf-8";
// $http({
// \t \t \t url : 'charts',
// \t \t method : "POST"
// \t \t }).then(function(response) {
// \t \t \t sampleData =JSON.stringify(response.data);
// \t \t \t }); \t
//
// prepare jqxChart settings
var settings = {
title: "Enrollment Status",
description: "State-Wise Enrollments",
enableAnimations: true,
showLegend: true,
padding: { left: 5, top: 5, right: 5, bottom: 5 },
titlePadding: { left: 40, top: 0, right: 0, bottom: 10 },
// source: $scope.chartdata,

},

seriesGroups:
[
{

columnsGapPercent: 100,
seriesGapPercent: 5,

displayValueAxis: true,

axisSize: 'auto',

gridLinesColor: '#777777'
},
series: [
{ dataField: 'AccountsOpened', displayText: 'AccountsOpened' },
{ dataField: 'VerificationPending', displayText: 'VerificationPending' },
{ dataField: 'Rejected', displayText: 'Rejected'}
]
}
]
};
$scope.chartSettings = settings;
});
這不工作..仍然是同樣的問題 – RD063
